Answer:
y divided by 6 1/4 = 11 3/4
Step-by-step explanation:
First, change the mixed numbers into improper fractions:
y divided by 25/4 = 47/4
Next, multiply both sides by 25/4:
y divided by 25/4 x 25/4 = 47/4 x 25/4
The 25/4's on the left side of the equation cancel each other out, leaving you with:
y = 47/4 x 25/4
Multiply 47 x 25 and keep the same denominator:
y = 1,175/4
Divide and:
y = 293 3/4
Answer: adult ticket = 131 , student ticket = 262
Explanation:
Let x be the number of student ticket
Let y be the number of adult ticket
x + y = 393
x = 2y
Substitute x value:
2y + y = 393
3y = 393
y = 131
Substitute y value in one of the equation above:
x = 2(131)
x = 262
Answer:
<em>20 boys </em>
Step-by-step explanation:
b = 2g
100% - 20% = 80%
80% ÷ 2 = 40% = 0.4
0.4g = 4 ⇒ g = 4 ÷ 0.4 = 10
b = 2 × 10 = 20
There are 10girls and <em>20 boys</em> study in the class.
